Methods: This study consolidated 65 use case scenarios from key academic and institutional 6G sources into 21 representative cases. A three-round Delphi-based expert assessment, employing a five-point Likert scale and interquartile-range-based consensus monitoring, was used to assign primary and secondary technical requirements across six core dimensions: immersive communication, massive communication, hyper-reliable low-latency communication, integrated sensing and communication, integrated artificial intelligence and communication (IAAC), and ubiquitous connectivity. A three-dimensional (3D) prism-based visualization framework was subsequently developed to represent the interdependencies among these requirements. Results: IAAC and massive communication emerged as the most critical requirements, each functioning as a primary or secondary driver across most use cases. The prism framework revealed hierarchical and complementary relationships among the six dimensions that conventional 2D wheel diagrams cannot adequately capture. Furthermore, a nine-criterion multidimensional classification framework, encompassing data transmission mode, decision-making mode, communication flow, interaction type, device type, deployment type, human activity innovation, user type, and personalization level, was developed, offering industry-specific guidance for service design. Collectively, the proposed framework supports user-centric design, informs strategic technology planning, and contributes to policy development while acknowledging existing limitations in quantitative mapping and economic analysis.<\/jats:p>","DOI":"10.3390\/systems14040404","type":"journal-article","created":{"date-parts":[[2026,4,7]],"date-time":"2026-04-07T09:40:31Z","timestamp":1775554831000},"page":"404","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prism-Based Mapping of 6G Use Cases Integrating Technical Requirements and Multidimensional Service Classification"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9011-0550","authenticated-orcid":false,"given":"Sunhye","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Industrial & Systems Engineering, Dongguk University, 3-26, Pil-dong 3-ga, Chung-gu, Seoul 100-715, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoon","family":"Seo","sequence":"additional","affiliation":[{"name":"Department of Industrial & Systems Engineering, Dongguk University, 3-26, Pil-dong 3-ga, Chung-gu, Seoul 100-715, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7629-7865","authenticated-orcid":false,"given":"Seung-Hoon","family":"Hwang","sequence":"additional","affiliation":[{"name":"Division of Electronics and Electrical Engineering, Dongguk University, 3-26, Pil-dong 3-ga, Chung-gu, Seoul 100-715, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1110-4011","authenticated-orcid":false,"given":"Byungun","family":"Yoon","sequence":"additional","affiliation":[{"name":"Department of Industrial & Systems Engineering, Dongguk University, 3-26, Pil-dong 3-ga, Chung-gu, Seoul 100-715, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e4233","DOI":"10.1002\/ett.4233","article-title":"6G: A comprehensive survey on technologies, applications, challenges, and research problems","volume":"32","author":"Mahmoud","year":"2021","journal-title":"Trans.
